A sumptuous wedding banquet is being held in the ballroom of a luxurious hotel. While the bride CHO LAI-MEI and her father CHO KING-TIM are waiting in the bridal room, a shot is suddenly fired. Senior Chemist of the Forensic Science Division PO KWOK-TUNG is summoned to the hotel to collect evidence while playing with his daughter. LEE CHIN-FUNG and LING SIN-YEE of the Regional Crime Unit find three corpses upon their arrival at the ballroom. Later YEE discovers one more body under the table. After receiving a call from her teammate, YEE goes to another hotel room to have a look. TUNG follows her to the site, and after a careful investigation, they believe that one suspect is in hiding. While Senior Forensic Pathologist CHUNG HOK-SUM is conducting an initial examination, the ceiling spotlight hanging over one of the corpses becomes unfastened and falls down suddenly. Suspect CHI-WAI is questioned by FUNG and YEE.… ...

All the evidence at hand suggests that FU is the killer’s real target but it is still incomprehensible why the bride ends up being shot instead. YEE and FUNG go to see FU but are shocked to see him being pursued by a man. YEE takes FU to the emergency room, where they run into SUM. SUM notices a dark red scar on FU’s waist and quickly tells YEE about this. Scientific Evidence Officer CHEUNG CHEUK-KWAN examines the stain left on the clothes of one of the shootout victims HO-LEUNG, and later determines that it is bluefin tuna oil. YEE learns from the sushi chef that LEUNG had come to see his apprentice CHI before his death. SUM has accidentally spilled some coffee on a girl named CHEUNG-LING at a convenience store, who is later found to have vitiligo on her face. SUM stalks LING for a while and catches her meeting CHI in secret. YEE and FUNG go to see TIM. But before they can reach him, TIM has fallen off the rooftop.

YEE and FUNG find FU on the rooftop, who is trembling with fright and starts bleeding from his waist. TIM and FU are both sent to hospital while TUNG and his colleagues are heading for TIM’s mansion for evidence collection. FUNG comes to take statements from TIM, during which TIM reveals that FU is trying to blackmail him for money with nude photographs of MEI. SUM goes to the hospital to conduct a forensic examination of FU and TIM. Having cross-checked her findings with those from TUNG, SUM has finally found out the truth. TUNG reveals to his lawyer wife YIK-FEI that the Parent-Teacher Association chairman would like to close down the watercolor painting class which their daughter MAN has been attending. Thinking that it is a grossly unfair arrangement, FEI is not going to let it pass. SUM and YEE listen to a supernatural show on the radio, in which the “Sky Eye Girl” KA-MAN makes a prophecy.… ...

KA-MAN reveals to the business magnate KWOK FU-WAH a prophecy predicting his death. Feeling offended, KAM TAI-YAM, who is standing next to WAH, gives KA-MAN a telling-off and picks a quarrel with LUK CHUN-KWONG, also known as Rev LUMINOUS, a feng-shui master who has been assisting KA-MAN. The police have found WAH’s body on a mountain slope. SUM notices a number of horizontal wounds on WAH’s back but his front is unscathed. YEE and FUNG come to take statements from WAH’s wife MEI-FUN, and can tell from what she says that she is deeply in love with her husband. SUM submits the autopsy report to TUNG. After a detailed study of the report, TUNG believes that WAH’s death is a case of murder. KWONG and KA-MAN are summoned to the police station for questioning, during which KWONG explains that the feng-shui technique he taught WAH is for lifespan extension and avoidance of bad luck.… ...

FUN appoints FEI as her legal counsel, who is very confident of winning the case. YEE and FUNG go to the magazine’s office to look for clues. Staff of the Forensic Science Division get to watch a video clip of FUN and YAM recorded by a reporter, although they cannot hear what the pair are talking about. FEI who is working at home overhears TUNG talking on the phone, during which he suggests enlisting an expert to help decode the conversation between FUN and YAM. FUN is not happy with FEI’s attitude and decides to dismiss her. TUNG sees through FEI and begins to realize the gap between them. POK-SZE asks SUM to join him in observing KA-MAN. KWONG holds a prayer rally, attracting a large flock of worshippers who have come for KA-MAN’s buns.
